Judy and Nick Wilde eventually solve the case and locate all of the missing mammals, which are being held captive by Mayor Lionheart at the Cliffside Asylum. They also discover that they have all gone savage.

Later in the film, Judy discovers that night howlers are responsible for making the missing mammals savage and Bellwether is behind the conspiracy.

Emmitt wakes up after his treatment

At the end of the film, it is reported by the ZNN that an antidote for the night howler serum the missing mammals have been exposed to has been created, thus curing them all.
